Question

I tried all the commands and suggestions available in stackoverflow and online but none worked

• https://stackoverflow.com/a/13366444/1441666
• https://stackoverflow.com/a/28018008

and many more but nothing works for me

I am getting below error - None of below commands are working.

$adb root
$adb disable-verity

For

$adb remount
remount of / failed: Permission denied
remount failed

So then I tried with different commands like

$ adb shell mount -o rw,remount /system
mount: '/system' not in /proc/mounts

$ adb shell mount -o rw,remount /
'/dev/root' is read-only


$ adb shell  mount -o rw,remount -t /dev/block/stl12 system
mount: 'system' not in /proc/mounts

$ adb shell "su 0 mount -o rw,remount /system"
mount: '/system' not in /proc/mounts

$ adb shell
$ su
# mount -o rw,remount /system

 mount: '/system' not in /proc/mounts

I had the same issue.The solution is to mount the root (/). After this you can write to /system.

mount -o rw,remount /

Don't forget to reset the state to 'ro'.

mount -o ro,remount /
